    Hi,
    I have just reintroduced the BrRdoModuleMult and BrRdoMult classes.  The
    ModuleMult class uses BrTileModuleMult and BrSiModuleMult classes to set
    up the calibrations (hopefully allowing for a
    more transparent transition to using the DB for these calibrations) but
    otherwise works independently of
    these classes.  My hope is to gradually move over to the new class
    structure, but I want to make the transition gradually, checking for
    errors along the way. Also, it is not clear to me what parts of
    Christian's code various people are using and so I didn't want to break
    active code.
    
    I believe the reintroduced classes "play nicely" with the newer NBI
    code.  I have placed the multStatus
    program in /brahms_app/sjs_app
    which now creates an NTuple containing JH original centrality, the NBI
    multiplicity, and the
    Si+Tile multiplicities and  corresponding centrality that is discussed
    in the analysis note that
    Hiro and I wrote.
    
    In the original analysis note, a sum multiplicity is quoted for the Si
    and Tile detectors.  The
    BrRdoModuleMult multiplicity is the average of the Si and Tile values,
    accounting for the solid angle difference in the two sets of detectors.
    We plan to revise the analysis note (and code) to eventually quote an
    equivalent multiplicity into -2<=eta<=2 range, but this has not yet been
    done.
